PURPOSE: An anode body of a magnetron is provided to stabilize a frequency characteristic of a magnetron by forming a potential difference between the first rods and the second rods as a π-mode. CONSTITUTION: Rods(110,130) of N number are adhered on an inner face of an anode cylinder(100) in a constant interval. The first rods(110) of N/2 number are directed to an upper end portion of the anode cylinder(100). The second rods(130) of N/2 are directed to a lower end portion of the anode cylinder(100). A constant height difference(h) is formed between the first rods(110) and the second rods(130). An anode body is formed by installing the first strap(150) on an upper portion of an opening portion of the first rods(110) and the second strap(160) on an upper portion of opening portion of the second rods(130). A phase difference between the first rods(110) connected with the first strap(150) and the second rods connected with the second strap(160) is 180 degrees.
